在简码中使用 get_the_terms

问题描述

我编写了一个轻量级插件来生成自定义分类法中所有术语的列表，效果很好。我想修改它以生成特定帖子的所有条款列表，但我正在努力寻找正确的方法来获取_the_terms

function antls_taxonomy_list( $atts ) {
    $atts = shortcode_atts( array(
        'post_id' => '','name' => 'category','hide_empty' => false,'exclude' => '','include' => '','order' => 'ASC',),$atts);


    $terms = get_the_terms( array(
        'post_id' => '','taxonomy' => $atts['name'],'hide_empty' => $atts['hide_empty'],'orderby' => 'name','order' => $atts['order'],'parent'   => 0
    ) );

完整代码如下（带有建议的模组），目前正在生成“此网站出现严重错误”消息

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}
 
define('ANTLS_PLUGIN_DIR_URL',plugin_dir_url( __FILE__ ) );

add_shortcode( 'tax_taxonomy_list','antls_taxonomy_list' );

function antls_taxonomy_list( $atts ) {
    $atts = shortcode_atts( array(
        'post_id' => '',$atts);

    global $post;
    $terms = get_the_terms( array(
        'post_id' => $post->ID,//ID from the $post object
        'taxonomy' => $atts['name'],'parent'   => 0
    ) );

    $html .= '<ul class="antls tax-list-'.$atts['name'].'">';

    if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
        foreach ( $terms as $term ) {
            
            if( !empty( $atts['exclude'] ) ) {
                $exclude = explode( ',',$atts['exclude'] );
               if( in_array( $term->term_id,$exclude) ) {
                    continue;
                }
            }
            
            if( !empty( $atts['include'] ) ) {
                $include = explode( ',$atts['include'] );
                if( !in_array( $term->term_id,$include) ) {
                    continue;
                }
            }
                
            $html .= '<li class="tax-item-'.$atts['name'].'" data-taxname="'.strtolower( $term->name ).'">';
            $term_link = get_term_link( $term );

            $html .= '<a href="' . esc_url( $term_link ) . '">' . $term->name . '</a>';      
            
            $html .= '</li>';
        }
    }
    
    $html .= '</ul>';
    return $html;
}

解决方法

在短代码中传递 id 属性会做到这一点。

//Static
[shortcode id="123"]

//Dynamic. Get the ID of the current post
global $post; //Declare global post variable
 $terms = get_the_terms( array(
    'post_id' => $post->ID,//ID from the $post object
    'taxonomy' => $atts['name'],'hide_empty' => $atts['hide_empty'],'orderby' => 'name','order' => $atts['order'],'parent'   => 0
 ) );
